Detailed Description

The 1/2" poppet type check valve with male × female NPT connections is designed to allow fluid flow in one direction while preventing backflow in oil and gas systems. Its poppet mechanism provides fast response and a positive seal under pressure, protecting pipelines, pumps, and equipment from reverse flow and pressure fluctuations.

The 1/2" size is suitable for medium diameter lines, instrumentation, sampling, and control applications where reliable uni-directional flow is required. Male × female connections enable secure inline installation and integration into existing piping systems without additional fittings, reducing potential leak points and simplifying system layout.

The valve has a standard working pressure of 6000 psi, with optional configurations up to 10000 psi. Selectable cracking pressures range from 1/3 to 25 psi, allowing precise adaptation to system requirements. Construction materials include corrosion-resistant SS 316, SS 316L, Duplex, Super Duplex, Hastelloy C276, Inconel 625, Monel 400, and Brass, ensuring durability in demanding oil and gas environments.

All valves are factory tested for cracking and reseal performance, with pneumatic testing at 1000 psig to verify seat integrity. Heat code traceability ensures quality and material verification, and additional testing including vibration, temperature, and helium is available for critical applications requiring high reliability.
